摘要: The objective of this study was to evaluate the performance and quantitative characteristics carcass immunocastrated, barrows females in finishing phase fed with diets containing 10ppm ractopamine. One hundred twenty animals were used, initial weight 99.1±5.3kg, distributed a randomized blocks factorial design 2 x 3 (two ractopamine levels, 0 three sex), five replicates four each. inclusion diet improved (P 0.05) pigs. sex determining factor traits had higher (P<0.05) hot yield for immunocastrated male they have above barrows. Immunocastrated males percentage lean meat results highlight need studies adjust nutrient levels
